The author retested frontier models using the full version of SlopCodeBench (36 questions, 196 checkpoints per setting). The highest was GPT-6 Astra with a strict pass rate of 16.3%, above GPT-5.5's 14.8% in May, with the tested models overall ranging from 12.2% to 16.3%. In the three full comparisons, the XHigh tier cost 2.11-4.22 times that of Medium, but Opus 5.5 actually had more strict passes at the Medium tier (28 vs. 25), while Astra and SOL performed better at the XHigh tier.

Django co-creator Simon Willison used a single English prompt to have Claude Opus 5.5 add a four-player battle map to his web game and rework the networking code to support four-player multiplayer. The prompt gave only four constraints—four-way rotational symmetry, at most four AI players, building on the existing WebSocket non-audio multiplayer mode, and empty slots filled by AI—without specifying files or lines of code. Based on this, the author argues that prompts should include fewer steps a

The Claude Blog discusses when to fold sub-agents into the main loop when building Agents, arguing that on the Claude Platform, a single main loop plus on-demand loading of Skills/tools often yields better quality and lower cost and latency across multiple internal comparisons. The article notes that one sub-agent per team plus aggregate orchestration often replicates the organizational chart, bringing problems such as context loss, Frankenprompts, and localized evals; one customer, when compari

The author used 50 short messages to test Claude Fable 5.1's image steganography capability: when only asked to hide a specified sentence in an image, the model spontaneously encoded it using visual attributes such as object height; in a separate new session given only the rendered PNG, the same model could still decode about 78% (39/50). In cross-decoding, Fable encoding with Astra decoding achieved an 88% success rate (44/50), Astra encoding with Fable decoding achieved 84% (42/50), and Astra'

Lecture 9 of Stanford's CS 329Z course presents a selection diagram for Agent system optimization: the prerequisite for optimization is having data, a system, and evaluation metrics all in place; generally, context optimization (prompts and few-shots) is done first because it is cheap, fast, and sample-efficient; when context optimization is insufficient, or when you want to distill capabilities into a small model, or when prompts grow longer and longer, then you move on to changing the weights.
